How about implementing FromStr instead? That's more common for parsing things from a string.
| fn from_string() { | ||
| let device_id = DeviceId::try_from("hci0/dev_11_22_33_44_55_66"); | ||
| assert_eq!(device_id.unwrap().to_string(), "hci0/dev_11_22_33_44_55_66"); | ||
| } |

Please add a test for converting an invalid path String to a DeviceId too, to make sure it returns an error as expected.

actually i did some digging and turn out that dbus::Path returns Result<Path, Infallible> so it always succeeds and should never produce an error, so i ended up with adding simple validation (check if input starts with hci)

It looks to me that Path::try_from is an auto implementation based on Path::from, which in turn will panic if there is an invalid path. But Path::new will return an error.

Why do you need to map the error here?
